告一:Data security and privacy protection authentication scheme in TMIS(马文平 教授)112日下午14:00-1530

   要: Telecare Medical Information System (TMIS) network is a typical functional network, which integrates various types of mobile devices and communication technologies to upgrade the traditional face-to-face medical treatment model to intelligent one, which can provide the flexible and convenient e-health care. Real-time and comprehensive information collection, storage, sharing and processing functions for the personalized medical service are provided in TMIS. The privacy and security risks in TMIS are the main obstacles to the wide deployment of (TMIS). Traditional public key cryptography (PKC) systems support confidentiality and integrity for data storage. However, traditional PKC systems can only provide many-to-one access control service, thus cannot meet the requirement for flexible data sharing. The new emerging cryptology systems including blockchain technology, secret sharing algorithm, attributed-based encryption, not only realize fine-grained access control mechanism, but also ensure data security.

报告人简介: Wenping Ma received the B.S. and the M.S. degrees in basic mathematics from Shaanxi Normal University, Xi’an, China, in 1987 and 1990, respectively, and the Ph.D. degree in communication and information system from Xidian University, Xi’an, China, in 1999. He was a Post-Doctorial Fellow with Chonbuk National University, Jeonju, South Korea, from 2003 to 2004, and acted as a senior visiting scholar in South Korea from 2004 to 2005. He is currently a Professor with the State Key Laboratory of Integrated Service Networks, School of Telecommunications Engineering, Xidian University, Xi’an, China. His research work mainly focuses on information theory, communication theory, error correcting code and information security.


告二:基于SM9数字签名算法的盲签名方案(何德彪 教授)112日下午15:30-1700

   要:SM9是由国家密码管理局颁布的一种标识公钥密码算法,主要用于数字签名、数据加密、密钥交换以及身份认证等。盲签名就是接收者在不让签名者获取所签署消息具体内容的情况下所采取的一种特殊的数字签名技术,在电子现金、电子投票等多个领域有着广泛应用。为了推广SM9算法在这些领域的应用,我们提出了一种基于SM9数字签名算法的盲签名方案,并给出了安全性证明。通过我们的方案可以产生SM9的盲签名,保护了用户的隐私。

报告人简介:何德彪,博士,武汉大学国家网络安全学院教授,博士生导师。研究方向包括:应用密码学、区块链安全、云计算安全、物联网安全等。2009毕业于武汉大学数学与统计学院应用数学专业,获理学博士学位。近年来,在IEEE TIFSIEEE TDSCScience China-Information Sciences等国内外著名期刊/会议上发表学术论文100余篇。主持国家自然科学基金、国家科技部“网络空间安全”重点专项子课题、教育部博士点基金、湖北省自然科学基金等20余项科研项目。获得教育部自然科学奖一等奖1项;获得国际知名期刊IEEE Systems Journal2018年最佳论文奖;担任中国计算机学会区块链专委会常务委员、中国密码学会学术工作委员会委员、中国密码学会组织工作委员会委员和中国密码学会青年工作委员会委员;担任Mathematical Reviews特约评论员;担任IET Wireless Sensor SystemsJournal of Medical SystemsComputers & Electrical Engineering等多个国际知名期刊的编委。

告三:Provably secure proactive secret sharing without the adjacent assumption(夏喆 副教授)112日下午17:00-1830

   要:Proactive secret sharing (PSS) not only shares the secret among a number of parties, but also divides the lifetime of the secret into many short time periods. The parties jointly update their secret shares in each time period, so that if the adversary cannot break into enough parties in a single time period, her compromised shares will become obsolete after the shares being updated. However, most of the existing PSS schemes require the adjacent assumption, i.e. if a party is corrupted during an update phase it is corrupted in both time periods adjacent to that update phase. In this talk, we demonstrate that this assumption not only hinders the security model to capture the mobile adversary’s abilities, but also prevents PSS schemes being used in many real-world applications. To solve this issue, we propose the first PSS scheme that is provably secure without the adjacent assumption。

报告人简介:夏喆,男,1982年7月出生,博士、武汉理工大学副教授、硕士生导师。2009年获得英国萨里大学(University of Surrey)博士学位,2009年至2013年在英国萨里大学从事博士后研究,2017年至2018年在澳大利亚伍伦贡大学(University of Wollongong)进行访问学习,主要研究方向为密码学和安全协议。近年来在TIFS、IET Information Security、ACISP、Indocrypt等国际期刊会议上发表学术论文40余篇,曾担任澳大利亚学术委员会(ARC)信息安全方向评审及ESORICS、EVT等国际学术会议程序委员会委员。目前担任中国计算机学会推荐国际期刊《Journal of Information Security and Application》的副主编及多个信息安全专刊的编委。
